Application filed J'une 16, 1908. Serial No. 438,748.

T 0 all whom it may concern:

Be it known that I, HENRY LEIDEL, a citizen of the United States, and a resident of the city of New York, Richmond Hill, borough of Queens,in the county of Queens and State of New York, have invented a new and Im:

ed, with t e pitch'of the helix decreasing as.

the'ends of the strip are approached, whereby when the strip is withdrawn from the stem the nicotin andjother collected matter will.

not revolv'e and thus effect its escape, but Wlll pass out with the strip.

Reference 18 to be had to the accompanying drawings forming a partiof this specifica-' tion, in which similar characters of reference parts in all the views. Figure 1 1s a centra longitudinal section through a straight stem pipe having my improvement app ied thereto; Fig. 2 is a like sectional view through a curved stem pipe,

showing my im rovement; Fig. 3 is a per,

s ective view 0 the cleaner as used in the pipe shown in Fig. 1 and Fig. 4 is a perspec tive view of the cleaner as used in the pipe shown in Fig. 2.

' In Fi s. 1 and 2 I have shown pipes 5, 5, of conventlonal form, having stems 6, 6 respectively, the pipe in Fig. 1 bein of the stralght stem type, and the ipe in ig. 2 of curved stem construction. In applying myimprovements to these pipes I provide a strip 7- of sheet metal or other relatively stiff material of a width suitable to neatly fit within the stem of the pipe, which ordinarily necessitates the decreasing of width of that portion of the strip which is designed to ass into the removable portion of the stem, t 's reduction in the width of the strip forming shoulders 8, 8, at o posite sides which bear against the inner en of the removable portion of the stem and serve as a stop. The opposite end portions of the strip are helically formed or twisted, with the pitch decreasing as the extremities are approached, which is an important feature of my invention.

By this construction wlien the cleaner is placed within the stem, upon drawing it out I after the ipe has been used, the nicotin and other co ected-matter will be scraped off and travel lineally outward with the cleaner, whereas if the twisting were uniform, on

drawing the cleaner out of the pipe stem a rotary motion would be imparted to the nicotin which would effect its escape.

The cleaner is designed to remain in the pipe stem during the use of the pipe and is preferably of such length as to extend fronr one end of the stem to the other. In this manner, on cleaning the pipe,-itis only necessary to pull off the removable portion of the stem and draw the cleaner from the part of the stem in which it remains, which operation frees the smoke passage throughout its len th. After the cleaner is wiped off it is rep aced within the stem and the pipe is again ready for use.

The only difference in the construction of the cleaner for the two forms of pipes disclosed, is the curving of the outer end of the cleaner for the curved stem pipe, which does not make its removal and insertion difficult in view of the flexibility of the material of which the cleaner is made. i

I am aware that prior'to my invention,

pipe cleaners of the same general construe-- relatively stiff member having its end por I, however, believe that tions twisted, with the pitch decreasing esthe In testimony whereof I htve signed my extremities of said end portions are apname to this specification in the presence 0f 10 proacjlied. 1 l 1 two subscribingwitnesses.
